Application filed August25; 1927. Serial No 215,395.

The invention relates to a chock adapted to be seated on a railroadrailto be engaged by the car wheels to stop a car in place on a siding,and has for its object the provislon of a device of the character statedthat may be effectively seated on the rail and provided with anupstanding pedestal carrying a removable and replaceable brake shoe thatI improved chock showing'it applied to a railroad rail, suggestedinbroken lines, the car wheel being also indicated in broken lines,

Figure 2 isa top plan view of the chock, Figure 3 is a longitudinalsectional view of the chock,

Figure 4 is an end view, Figure 5 is a transverse sectional view on aplane indicated by theline 55 of Figure 1,

Figure 6 is a top plan view of the channelled member,

Figure 7 is a similar view of the channelled plates, and Figure 8 is atop plan view of the pedestal member, the brake shoe being removed.

In the drawings similar reference characters will be used to designatecorrespond ing parts throughout the several views.

The improved track chock comprises channelled member 1 having downwardlyturned side flanges 2. One end portion of the member 1 is upwardlyoffset as shown at 3 to receive a plate 4 that is secured thereto bymeans of rivets, or other suitable fastenings 5, and having side flanges6 alined with flanges 2, channelled member 1 and plate 4 being adaptedto seat on a railroad rail suggested at A. The free end of plate 4 istapered as shown at 7 to form a tread for car wheel B to carry the wheelup off of the rail onto the plate 4, and the offset portion 8 has itsupper edge inclined to provide a tread for the wheel to permit it toride up on to said offset portion. The end of channelled member 1 remotefrom the offset portion 3, is provided with a tongue that is upturned asshown at 8 and has its extremity returned to form a hook 9.

Secured to channel member 1 is a pedestal member 10 having a base plate11 seated on said channelled member and secured thereto "A t r MARTINHEEREN, or ivnwzron, OWA,

by meansof bolts 12 or other suitable'fasten- '7 ings, said base-plate11 having an upturned end 13 to engage the upturned tonguei8, and hasits extremity seated in the-hook 9, this structure providing forsecurely fastening the pedestal member 10 to the channelled member 1 andserving to strengthen the engagement by the bolt, to prevent shearing ofthe bolt under undue stress in the use of the device.

14 indicates the pedestalcarried by v the base 11 and recessed as shownat 15, the

upper edge of the pedestal being inclined as shown at 16 to support abrake shoe 17'having a flange on its upper and side edges, designated 18that encloses the upperportion of the pedestal, said brake shoe having adownwardly extending tongue 19 provided with a slotted'opening 20 toreceive a pin 21 secured to the walls of the pedestal to hold the brakeshoe in position. The function of said slotted opening 20 is to permitadjustment of the brake shoe when engagedby the V tread of the wheel toprevent breakage of the shoe and to insure engagement of the bearingsurface thereof with the wheel tread. 22 indicates a reinforcing bracemember connecting the forward end of the base 11 with" the upper portionof the pedestal 14:.

In use itwill be understood that the de vice is placed upon a railroadrail. such as suggested at A, in the position in which it is desired tostop the progress of a car in being located on a siding, and it will beunderstood that when the forward car wheel encounters the chock it willride onto the plate a and from thence tothe offset portion 30f thechan-- nelled member 1, and the-wheel will engage. the brakeshoe 17,thus stopping the wheel from further progress, and the brake shoe willalso serve to prevent spinning or rotating of the wheel. that by havingthe parts dismemberableas hereinbefore described that repairv of thechock may be'readily effected by replacing imperfect-parts withreplacement parts, this being particularly applicable to the brake shoe17 thatmay be readily removed and replaced should it become worn orbroken by contact with the wheel. I

What is claimed is A track chockfor car wheels, comprising a channelledmember having an upwardly offset portion at one end, the other end ofsaid member lip-turned and its extremity reb'ent to form a hook, apedestal secured to said channelled member and. having an lip-turnednelled plate having a tongue secured under the upwardly ofi'set portionofthe first-mentioned member said channelled member and plate beingadapted to seat on a railroad rail,

the pedestal provided with a recess, a brake shoe, a tongue onsaic'llorake shoe engaging in said recess and having'a slotted openingtherethrough, and securing means engaging said pedestal and through saidslotted opening. i

In testimony whereof I afliX my signature.

MARTIN I-IEEREN.
